NOOPING

ONFIGURATION

Use the IP Service > DHCP > Snooping (Configure Global) page to enable

DHCP Snooping globally on the switch, or to configure MAC Address

Verification.

"DHCPv4 Snooping" on page 905

ARAMETERS

These parameters are displayed:

◆

DHCP Snooping Status –

Enables DHCP snooping globally.

(Default: Disabled)

◆

DHCP Snooping MAC-Address Verification

– Enables or disables

MAC address verification. If the source MAC address in the Ethernet

header of the packet is not same as the client's hardware address in the

DHCP packet, the packet is dropped. (Default: Enabled)

◆

DHCP Snooping Rate Limit

– Sets the maximum number of DHCP

packets that can be trapped by the switch for DHCP snooping.

(Range: 1-2048 packets/second; Default: Disabled)

◆

DHCP Snooping Information Option Status

– Enables or disables

DHCP Option 82 information relay. (Default: Disabled)

◆

DHCP Snooping Information Option Sub-option Format

– Enables

or disables use of sub-type and sub-length fields in circuit-ID (CID) and

remote-ID (RID) in Option 82 information.

◆

DHCP Snooping Information Option Remote ID

– Specifies the

MAC address, IP address, or arbitrary identifier of the requesting device

(i.e., the switch in this context).

■

MAC Address

– Inserts a MAC address in the remote ID sub-option

for the DHCP snooping agent (i.e., the MAC address of the switch’s

CPU). This attribute can be encoded in Hexadecimal or ASCII.

■

IP Address

– Inserts an IP address in the remote ID sub-option for

the DHCP snooping agent (i.e., the IP address of the management

interface). This attribute can be encoded in Hexadecimal or ASCII.

■

string

- An arbitrary string inserted into the remote identifier field.

(Range: 1-32 characters)

◆

DHCP Snooping Information Option Policy

– Specifies how to

handle DHCP client request packets which already contain Option 82

information.

■

Drop

– Drops the client’s request packet instead of relaying it.

■

Keep

– Retains the Option 82 information in the client request, and

forwards the packets to trusted ports.
